Cryptography Challenge

Disclaimer: This challenge is also solved by Rohman (nenowo)

Upon downloading the cipher2.txt file, here is what we got 2126226{19122929121712_6121911821_26422_842928}

Since the first couple of flag formats must be RWSC letters, it is quite obvious that we need to use n r to letter decrypter

We get UZVF{SLBIBILQL_FLSKHU_ZDV_HDBIBH} as a result

Okay this part I have no clue how he did it, but after reading the solutions, the text was encrypted using Pizzini Cipher, and this is how he managed to find out that was the solution
